3. Opsætning
3.1 Kom godt i gang
Follow these steps to set up and begin using your UDIAG CR800:
- Tilslut til køretøj: Locate your vehicle's 16-pin OBDII Data Link Connector (DLC). This is typically found under the dashboard on the driver's side. Connect the CR800's OBDII cable to the vehicle's DLC.
- Tænd: The CR800 is powered directly from the vehicle's DLC, requiring no external battery. Once connected, ensure the vehicle's ignition is in the "ON" position (engine can be off). The device will automatically power on.
- Initial Communication: The device will automatically initiate communication with the vehicle's onboard computer. Allow a few moments for the connection to establish.

4. Betjeningsvejledning
4.1 OBDII Diagnostic Functions
The CR800 provides comprehensive OBDII diagnostic capabilities:
- Reading and Erasing-koder:
Navigate to the "OBDII/EOBD" menu. Select "Read Codes" to display current, pending, and permanent Diagnostic Trouble Codes (DTCs). To clear codes, select "Erase Codes" and confirm the action when prompted. This will turn off the Check Engine Light (MIL) after the underlying repairs have been completed.

- I/M-parathedsstatus:
Use the dedicated "I/M" hotkey to quickly check the readiness status of emission-related monitors. Green indicates ready, yellow indicates pending, and red indicates not ready. This function is crucial for determining if the vehicle is ready for a smog test.
Image 4.3: The I/M Readiness key provides a quick and easy way to check emission monitor status for pre-inspection tests.
- VIN Hotkey:
Press the "VIN" hotkey for one-click retrieval of the vehicle's Vehicle Identification Number. This eliminates the need for manual navigation through menus.
Image 4.4: The VIN hotkey allows for quick retrieval of the vehicle's identification number.
- DTC-opslag:
Use the "DTC" hotkey to access the built-in DTC library. Enter a code to view its definition, providing immediate insight into the nature of the fault without needing external resources.
Image 4.5: The DTC Lookup feature allows users to quickly find definitions for diagnostic trouble codes.
4.2 Battery Test Function
The CR800 includes a dedicated battery testing feature:
- Realtid Voltage Display:
Select "Battery" from the main menu to monitor the vehicle's battery voltage in real-time. This function helps assess battery health and prevent unexpected starting issues by providing timely information on battery condition.
